Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25818, here are decompositions:

  • 17 + 25801 = 25818
  • 19 + 25799 = 25818
  • 47 + 25771 = 25818
  • 59 + 25759 = 25818
  • 71 + 25747 = 25818
  • 101 + 25717 = 25818
  • 139 + 25679 = 25818
  • 151 + 25667 = 25818

Showing the first eight; more decompositions exist.
